Dear all
We was able to modify MFG tool for eMMC flashing in our custom Automotive I.MX6 UL board
Micron 4.4.1 2GB
After failing
BOOTCFG1: 0X6D
BOOTCFG2: 0XCA 8 bit DDR
We tried
BOOTCFG1: 0X6D
BOTCFG1: 0X0A 1 bit SDR
And it works!
2 of 10 boards booted fine from eMMC
Can I now program for 8 bit SDR ?
-------------------------------------------------------------------------------
-------------------------------------------------------------------------------
8 of 10 boards show "Card did not respond to voltage select!" when triing to flash with MFG Tool
Its strange that 8 boards were bad assembled so i hope its a software error
-------------------------------------------------------------------------------
-------------------------------------------------------------------------------
How can i ensure sd is working in 8 bit mode + DDR
King Regards!
